If new people coming from outside the region fill jobs in some acitivity, how does IMPLAN handle the jobs of spouses? For the Type II or SAM multipliers, household expenditures are based on a one-dollar change in income. So the new job created addes labor income to the region. The labor income is then passed to the per-dollar household consumption function and then spent in the region. The induced effect therefore is not directly related to employment, but rather to income generated. The IMPLAN model has no way of knowing if there are spouses working. You would have to treat this as a separate impact. If you do this, you would count the direct, indirect and induced results. If you think that spouses take a job, and its a new job to the region, then you should include it as a new event. If the spouse is taking a job that already exists in the region then in theory you should not count it, however, people often do.
